在使用Hive进行数据处理时遇到return code 2的错误，这可能由于向量化执行启用且数据量过大导致。为解决此问题，可以关闭向量化执行模式，通过设置`set hive.vectorized.execution.enabled=false`。日志显示了详细的错误堆栈，主要涉及MapReduce任务的MapOperator和MapJoinOperator。

今天突然进去跑不了数据老是报错return code 2 .之前可以跑通的。

日志如下

矢量查询(Vectorized query) 每次处理数据时会将1024行数据组成一个batch进行处理，而不是一行一行进行处理，这样能够显著提高执行速度。
可以通过设置
set hive.vectorized.execution.enabled = true; 但是如果数据量很大，她的batch就会很多，有可能导致return code -2

解决方法：
set hive.vectorized.execution.enabled=false; 控制是否启用查询执行的向量模式。
